Lawson’s here, but it doesn’t mean he’s happy

Manny Lawson, the 49ers’ disgruntled linebacker, is in Santa Clara for the team’s three-day minicamp. But that doesn’t mean everything is hearts-and-flowers on this front.

Lawson remains unhappy with his $625,000 salary for 2010, the final year of his contract, and his long-term plans are clouded.

“The 49ers are going to do what they feel is in their best interest, and Manny will do what’s in his best interest,” the player’s representative, Jonathan Feinsod, said early this afternoon. “Manny would like to be a 49er for the rest of his career, but that’s obviously not the 49ers’ plan right now.”

Yesterday, 49ers coach Mike Singletary declined to state whether the team planned to fine Lawson if he didn’t show up for the camp.

Lawson, who had 68 tackles, 6½ sacks and three forced fumbles a year ago while splitting time at outside linebacker, has yet to attend an offseason practice. The 49ers are scheduled to hit the field at 4 p.m. today to start the mandatory minicamp. Open locker room is at 12:45 p.m., which should give reporters a chance to talk to Lawson directly.

Cornerbacks Shawntae Spencer and Nate Clements also have skipped voluntary sessions this year, but not because of contract issues. They, too, are here, and like Lawson underwent physicals at Stanford this morning. But nose tackle Aubrayo Franklin, dissatisfied with his status as the 49ers’ franchise player, is not expected to participate.
